I've been reading about lighter components for the bike from new slip-ons to batteries. Obviously performance is the goal, but I didn't think about the benefits of reducing the bike's overall weight to increase HP. Questions:

1. Given that we've only got about 22HP to begin with, will making mods like these yield any noticable differences?

2. Might this also apply to rider weight (looking for a diet incentive )?

3. If #1 above is true, what other mods will reduce bike weight and improve performance?

Thanks!

That might be true (7 lbs = 1 HP) at the drag strip, but that's about the only place you'd notice any performance gains from moderate weight reduction (with exception of lighter wheels).

That ratio doesn't work for everything though, as a 7 pounds weight reduction for a 300 pound cycle would be a significantly larger percentage of it's overall weight than it would be for a 3000 pound car.

Reducing rider weight would be the easiest way to gain performance from weight reduction, as it's the biggest variable anyway.

I have a full Yoshi SS system and the DynoJet/DFC(HON-002) bike runs GREAT I could not be happier the work was done at www.rcalracing.com check with Rick

Like jkv stated I think it pertains mostly to drag racing/acceleration. When I was big into drag racing I know the general rule of thumb (for cars though which is apples to oranges with bikes) was for every 100lbs you shedded was good for another tenth in the quarter and every 10hp gained was another tenth. Not sure what the numbers are for bikes though.

+1 with WOOLF. However, I made the bike mods for my personal choice and enjoyment. Not to increase performance track wise. I owned several bikes before the ceebee and had little incentive to incorporate mods. I've picked up some knowledge along the way and put it into my bike......for my own reasons. Dropping the stock exhaust will also lighten the bike by about 30lbs. Our bike is light enough. Unless you plan on racing.

Gasoline at 68F/20C is about 6.2 lb per gallon...

so just ride around with a maximum half a tank of gas all the time and dont worry about dieting

A lot of people are going to lighter batteries to save a bit of weight. I was reading of a 500 AH battery that apparenty weighs just 3 pounds, I believe it was for race cars.

I think changing to a lighter exhaust must have a good cost-benefit tradeoff with the large weight saving available and a modest hp (1-2 hp) increase along with a possible mileage gain. They're expensive but some really good deals can be found.

Decreasing the riders weight and frontal area would offer good returns.
